SPECIFICATION forming part of Letters Patent No. 295,163, dated March 18, 1884.

Application filed June 21, 1883.

To aZZ whom it may concern.-

Be it known that 1, JOHN A. Gnovna citi-' zen of the United States, residing at Bluffton, in the county of Wells and State of Indiana, have invented certain new and useful Improvements in \Vindow-Screens; and I do declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to .which it appertains to make and use the same. reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention pertains to improvements in window-screens, having for its object, among other things, to readily adapt it to windows of different widths, to strengthen or re-eni'orce the wire-cloth at its upper and lower or free edges, and to stretch it tightly in position across the wiudow frarne openings and it consists of the combination. and arrangement of parts, substantially as hereinafter fully set forth and claimed.

In the accon'ipanying drawings, Figure 1 is aview of my improved screen applied to a window for use, and Figs. 2 to 6 are detail views thereof; and Figs. 7, S, and 9 are detail views, all of which will be described.

In the organization of my invention, I employ a sheet-metal or wooden strip, A, which is formed or provided with an angular flange, a, at its outer edge, which is suitably secured to the window-frame facing, and which serves in the capacity of a brace. B is a similar strip without the flange, which is slid under or behind the strip A, and connected adj ustably to it by means of headed rivets or projcctions a, projecting from the strip or plate A through horizontal slots, at, in the strip or plate B, as seen in Fig. 3, to permit the movement of the latter strip or plate in the direction of the width of the window, the purpose of which will be seen in connection with other devices presently described.

To the inner edge of the plate B (which is turned under to lap itself with the inserted wire-cloth) is connected one edge of the latter, (lettered 0,) lapped over the turned-nu der edge of the said plate, both which edges of the plate and wire-cloth are firmly bent together against the plate, thus effecting the union of said parts.

(No model.)

i D is a lever-ratchet and eccentric pivoted upon the plate or strip A, and having an eccentrically-disposed pin or projection, 12, working in a vertical slot, b, in plate or strip B, as seen in Figs. 2 and 3 in particular. With the ratchet of the lever or eccentric engages a pawl, c, hung upon the strip or plate A, to retain said lever at the desired point of its move ment or adj ustnicnt in properly stretching the screen.

E is an upright cylinder constructed in two parts-may also be in three parts-to which the other vertical edge of the wire-cloth is connected, and upon which the same is wound, as seen in Fig. 1. The lower axis or pintle of the cylinder E bears in a plate, at, it being provided with a socket to receive said-pintle, and with a slot, through which is driven into the sill a nail securing the said plate thereto. The upper pintle or axis of the cylinder E bears in a bracket, d, both which and the lower plate, (Z, are connected to the slat or bar F, disposed in the window-frame, and adapted to support the bracket (2, while the said plate and bracket secure the slat or bar F in posi tion. The bracket cl has an upwardly-projecting flange, (F, at one end, which is notched or slotted to adapt it to fit under the head of a screw or nail driven into the window-frame, as seen in Fig. 1. This bracket has also atone of its side edges a downwardly-projeating flange, d, which tits down against oneside of and assists to hold the slat or bar F in position. This bracket has on its upper side apertured studs or cars, which form bearings for a short horizontal shaft, 6, carrying a beveled cog-wheel, f, gearing with a similar wheel or pinion, g, on the upper end of the shaft of the cylinder E, said horizontal shaft e also having a crank or handle, g, to operate the said wheels and the cylinder E, to enable the tak ing up of surplus wire-cloth constituting the screen proper. A pawl, h, is hung upon a stud of the bracket d, and engages with the teeth of the cog-wheel f, to prevent the reverse movement thereof and of the roll, after the wire-clothhas been properly wound thereon.

To revert to the wire cloth or screen 0, it

will be seen that its upperand lower edges are re-enforced or strengthened by thickening the same, as at (3 Oit may be by making the said edges of iron, steel, brass, copper, or

any other pliable material, in the form of a band, chain, or series of links suitably woven Having thus fully described my invention, 1

claim and desire to secure by Letters Patent 1. In a window-screen, the combination, with the wire-cloth, of the plates or strips adjustable one upon the other, and means for the retention of the opposite edge of the cloth, substantially as and for the purpose set forth.

2. In a window-screen, the combination, with the screen proper, of the cylinder and its operating mechanism, and the plates or strips, one having an eccentric-lever and ratchet, and the other having slots, one of which receives a pin or projection of the eccentric-lever, and

the others receiving headed projections or rivets of the former plate, substantially as and for the purpose set forth.

3. In a window-screen, the combination, with the wire-cloth cylinder, of the bracket having the end flange projected upward therefrom, the lower bearing-platehaving a socket and slot, and the slat or bar arranged between the bracket and said plate, substantially as and for the purpose set forth. 4

4:. In a window-screen, the combination, substantially as described, of the wire-cloth, the adjustable plates A B, connecting one end of said cloth to the window at one side ofthe latter, the roller E, made fast to the other end of the cloth, and journaled in suitable supports secured in the opposite side of the window, the bevel-pinion g, secured on the said roller, and the bevetgear wheel f, provided with pinion g and meshed with pinion 9, all arranged and operating substantially as set forth.

5. In a window-screen, the wire-cloth having' its free edges re-enforced by flexible metallic strips suitably woven upon or into the cloth, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. GROVE.
